A Dublin punter has just won big with this outrageous golf bet

Si Woo Kim became the youngest victor of the Players Championship with a game and nerves well beyond his 21 years.

Kim fired a bogey-free final round of three-under 69 to snatch the title at 10-under 278 at TPC at Sawgrass in Ponte Vedra Beach, Florida, on Sunday (local time).

Kim also managed to take all the suspense from TPC Sawgrass.

Kim then parred the treacherous back nine - including the famous par-three 17th hole featuring an island green - to clinch a three-shot victory over Ian Poulter and Louis Oosthuizen.

After his victory in the Wyndham Championship last year, Kim is the fourth player in the last 25 years to win twice on the PGA Tour before the age of 22, following in the footsteps of Tiger Woods, Sergio Garcia and Jordan Spieth.

Kim has played in 19 events this year.

Poulter has been reluctant to play at Wentworth in recent years as he was not a fan of the greens, but all 18 have been replaced at the revamped West Course in a huge project overseen by Ernie Els, Paul McGinley and current Ryder Cup captain Thomas Bjorn.

3 - It was a bad day for 54-hole co-leader Kyle Stanley who closed with a 75 to finish in a tie for fourth. It was only the third albatross in the history of the tournament and the first on that hole.

"I really wish I could have that benefit", Kim, who is only the second South Korean after K.J. Choi to reign supreme at Sawgrass, told reporters through a translator Sunday.

"My form is good - I don't feel like I've got a lot out of my game over the last few weeks - but I've been working hard and hopefully the results will follow".

With 600 FedExCup points from the victory, Kim moved from No. 132 to No. 21 in the standings and is in position to make his second trip to the FedExCup Playoffs and the Dell Technologies Championship. He had to get through Tour qualifying school three times, the youngest (17 years, 5 months, 6 days) in his first go-around in 2012. "And I'm very glad I could practice with him". Today I felt like a couple of putts slid by, but I played well under pressure, barring that frightful second shot on the last.

"If you're on your game and playing well, that the things you do", Oosthuizen said. "You up-and-down when you're in trouble, you just don't give shots away. And never once did he look flustered at all".

He then returned to the Web.com Tour until he locked up his PGA Tour card for the 2015-16 season by finishing 23rd on the 2015 Web.com Tour priority list.

J.B. Holmes brought the wrong kind of a show - an 84, the highest final round of anyone who had at least a share of the 54-hole lead.
